The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] See also Figure 1 As shown, a fully automatic electrical testing system corresponding to a preferred embodiment of the present invention includes: a main tower device 100, including a first turntable 110 and a plurality of suction nozzle mechanisms 120 for picking up and placing products, the plurality of suction nozzle mechanisms 120 are evenly distributed on the first turntable 110 along the circumference of the first turntable 110, and the first turntable 110 is suitable for driving the suction nozzle mechanisms 120 to move to a transfer station; a sub-tower device 200, including a second turntable 210 and a plurality of carrier mechanisms 220, the plurality of carrier mechanisms 220 are evenly distributed on the second turntable 210 along the circumference of the second turntable 210, and the second turntable 210 is suitable for driving the carrier mechanisms 220 to move to a transfer station and an electrical testing station; an electrical testing device 300, which is arranged at the electrical testing station; wherein the carrier mechanism 220 includes a socket 221 that can absorb or release the product, and the socket 221 is suitable for being electrically connected to the product and the electrical testing device 300, respectively.

[0034] The present invention sets a main tower device 100 and a sub-tower device 200, and the first turntable 110 and the second turntable 210 cooperate with each other, so that the product can be continuously and quickly lowered from the suction nozzle mechanism 120 to different carrier mechanisms 220 at the transfer station, and the carrier mechanism 220 can be moved from the transfer station to the electrical testing station under the drive of the second turntable 210, so that the electrical testing device 300 is electrically connected to the socket 221 to perform electrical testing of the product, thereby realizing large-scale and efficient transfer and electrical testing of the product; in addition, the carrier mechanism 220 includes a socket 221 suitable for being electrically connected to the electrical testing device 300 and the product, and the socket 221 uses adsorption to fix or release the product, with a simple structure and more convenient product placement.

[0035] Furthermore, the axes of the first turntable 110 and the second turntable 210 are parallel to the vertical direction, and the first turntable 110 is located above the second turntable 210. The nozzle mechanism 120 at the transfer station is located directly above the carrier mechanism 220 at the transfer station, and the nozzle mechanism 120 is suitable for vertical lifting to place or remove the product from the carrier mechanism 220.

[0036] Furthermore, the main tower device 100 includes a mounting plate 130 located above the first rotating plate 110, and the mounting plate 130 is a fixed structure. Figures 2 to 4 As shown, the suction nozzle mechanism 120 includes a suction nozzle assembly 121 and a pressing assembly 122. The suction nozzle assembly 121 is installed on the first turntable 110 to absorb or release the product. The pressing assembly 122 is installed on the mounting plate 130, and it cooperates with the suction nozzle assembly 121 to drive the suction nozzle assembly 121 to move. By installing the pressing assembly 122 on the mounting plate 130, the load-bearing capacity of the first turntable 110 can be reduced, the service life of the first turntable 110 can be increased, and the use cost can be reduced. Of course, in other embodiments, the pressing assembly 122 can also be directly installed on the first turntable 110.

[0037] Furthermore, in one embodiment, the first turntable 110 is provided with a hole through it in the vertical direction, and the suction nozzle assembly 121 is inserted into the hole and can be lifted and lowered in the vertical direction. Preferably, in this embodiment, the suction nozzle assembly 121 includes a suction nozzle seat 1211 and a suction nozzle member 1212, the suction nozzle seat 1211 is fixed to a position close to the edge of the first turntable 110, the suction nozzle seat 1211 is provided with a hole through it in the vertical direction, the suction nozzle member 1212 can be movably inserted into the hole in the vertical direction, and in the vertical direction, the projection of the suction nozzle member 1212 does not overlap with the projection of the first turntable 110, so as not to hinder the lifting and lowering of the suction nozzle member 1212. With the above structure, the first turntable 110 does not need to be provided with a hole for accommodating the suction nozzle member 1212, which improves versatility and facilitates the disassembly, assembly and replacement of the suction nozzle assembly 121.

[0038] Preferably, the nozzle assembly 121 includes a first linear bearing 1213 coaxially fixed in the opening of the nozzle seat 1211, and the nozzle piece 1212 is a round rod-shaped structure, which is adapted to the first linear bearing 1213 to be inserted into the first linear bearing 1213 and can move along the axial direction of the first linear bearing 1213. Since the structure of the nozzle seat 1211 is relatively complex and the cost is high, by adopting the above structure, the nozzle piece 1212 does not directly contact the nozzle seat 1211, thereby preventing the nozzle seat 1211 from being worn, and after long-term use, only the worn first linear bearing 1213 needs to be replaced, which effectively reduces the cost.

[0039] In addition, a first upper fixing block 1214 is fixed to the upper end of the suction nozzle member 1212, and a lower fixing block 1215 is fixed to the lower end, so that the suction nozzle member 1212 is limited by the first upper fixing block 1214 and the lower fixing block 1215 in the vertical direction to prevent it from being separated from the suction nozzle seat 1211. In this embodiment, the upper and lower ends of the first linear bearing 1213 both protrude from the suction nozzle seat 1211, and the upper and lower ends of the suction nozzle member 1212 both extend out of the first linear bearing 1213. The first upper fixing block 1214 and the lower fixing block 1215 are fixed to the extended portion of the suction nozzle member 1212. When the suction nozzle member 1212 moves downward to the limit position, the first upper fixing block 1214 can be abutted against the upper end of the first linear bearing 1213, and when the suction nozzle member 1212 moves upward to the limit position, the lower fixing block 1215 can be abutted against the lower end of the first linear bearing 1213.

[0040] Further, the pressing assembly 122 includes a first mounting seat 1221, a pressing rod 1222, and a pressing driving member 1223. The first mounting seat 1221 is disposed on the mounting plate 130 and is located above the suction nozzle assembly 121. The first mounting seat 1221 is provided with an opening through it in the vertical direction, and the opening on the first mounting seat 1221 is coaxial with the opening on the suction nozzle seat 1211. The pressing rod 1222 is disposed in the opening of the first mounting seat 1221 and can be lifted and lowered in the vertical direction.

[0041] Preferably, a second linear bearing 1224 is fixed in the opening, and the pressure rod 1222 is adapted to the second linear bearing 1224 to be inserted into the second linear bearing 1224. The second linear bearing 1224 does not protrude relative to the first mounting seat 1221, and the upper and lower ends of the pressure rod 1222 both extend out of the first mounting seat 1221. A second upper fixing block 1225 is fixed to the upper end of the pressure rod 1222 to prevent the pressure rod 1222 from being disengaged from the first mounting seat 1221 downwardly, and the lower end of the pressure rod 1222 abuts against the upper end of the suction nozzle 1212.

[0042] The pressing driving member 1223 is fixed to the mounting plate 130, and a cam 1226 is provided at the output end of the pressing driving member 1223. The cam 1226 pushes the pressing rod 1222 downward in response to the action of the pressing driving member 1223. Specifically, the pressing driving member 1223 is a rotary motor, and its rotation axis is parallel to the vertical direction. The upper end of the pressing rod 1222 is provided with a first follower 1227, which is specifically a cam bearing follower, which is fixed to the second upper fixing block 1225. The first follower 1227 is in contact with the cam 1226. When the pressing driving member 1223 drives the cam 1226 to rotate, the first follower 1227 is adapted to move downward under the push of the cam 1226.

[0043] Preferably, the nozzle mechanism 120 includes a first reset member 123 acting on the nozzle assembly 121 and a second reset member 124 acting on the pressing assembly 122. The first reset member 123 is suitable for driving the nozzle assembly 121 to rise and reset so that the pressure rod 1222 can reliably act on the nozzle member 1212. The second reset member 124 is suitable for driving the pressure rod 1222 to rise and reset so that the first follower 1227 is always in contact with the cam 1226, ensuring that the cam 1226 can reliably act on the pressure rod 1222.

[0044] Specifically, the first reset member 123 and the second reset member 124 are both springs. The first reset member 123 is sleeved outside the suction nozzle member 1212, and its two ends are abutted between the suction nozzle seat 1211 and the first upper fixed block 1214. The second reset member 124 is sleeved outside the pressure rod 1222, and its two ends are abutted between the first mounting seat 1221 and the second upper fixed block 1225. Preferably, the upper end of the second linear bearing 1224 is recessed inward relative to the top of the first mounting seat 1221, and the lower end of the second reset member 124 is received in the opening and abutted against the second linear bearing 1224 to improve the reliability of the second reset member 124 after installation.

[0045] Further, refer to Figures 5 to 7 As shown, the socket 221 is recessed from its top surface to form a receiving groove 2211, which is suitable for positioning and adsorbing products. The inner contour of the receiving groove 2211 is adapted to the outer contour of the product, and the inner wall of the receiving groove 2211 is provided with an electrical connection structure so that the product placed in the receiving groove 2211 is electrically connected to the socket 221. The bottom of the receiving groove 2211 is provided with an adsorption hole, which is connected to the external vacuum generating structure to provide an adsorption force to the bottom of the receiving groove 2211 to adsorb the product.

[0046] However, with the above structure, during the high-speed rotation of the second turntable 210, the product may fly out of the receiving groove 2211 under the action of centrifugal force. As a preferred embodiment, the carrier mechanism 220 includes a carrier seat 222, a cover assembly 223 and a transmission assembly 224. The carrier seat 222 is arranged on the second turntable 210, and the socket 221 is arranged on the carrier seat 222. The cover assembly 223 is arranged on the carrier seat 222, and the cover assembly 223 can be moved in the horizontal direction to a closed state to cover the receiving groove 2211, or moved to an open state to open the receiving groove 2211. The transmission assembly 224 is connected to the cover assembly 223, and the sub-tower device 200 includes a switching mechanism 230 located at the transfer station, and the transmission assembly 224 is suitable for driving the cover assembly 223 to switch to an open state under the drive of the switching mechanism 230, and when the switching mechanism 230 is deactivated, the cover assembly 223 is suitable for resetting from the open state to the closed state. By adopting the above structure, the switching mechanism 230 does not need to be set on the second turntable 210, which reduces the burden on the second turntable 210, and only one needs to be set, which simplifies the structure of the sub-tower device 200 and improves the service life of the second turntable 210. When the carrier mechanism 220 moves to the transfer station, the switching mechanism 230 can act on the cover assembly 223 to switch it to an open state to avoid hindering the placement of products. When the switching mechanism 230 does not act on the cover assembly 223, it can be reset to a closed state, thereby preventing the product from flying out of the receiving groove 2211 from the carrier mechanism 220.

[0047] Specifically, the second turntable 210 is recessed inward from its outer peripheral side to form a first mounting groove 211, and the first mounting groove 211 passes through the top and bottom of the second turntable 210 in the vertical direction. The carrier seat 222 is fixedly embedded in the first mounting groove 211. There are multiple first mounting grooves 211, and they correspond one-to-one to the carrier seats 222.

[0048] The carrier seat 222 is provided with a first mounting hole 2221 in the vertical direction, the socket 221 is fixed in the first mounting hole 2221, and the bottom of the socket 221 is provided with an electrical connection structure for electrically connecting to the electrical measuring device 300. The carrier seat 222 is recessed inward from its top surface in the vertical direction to form a second mounting groove 2222, and the cover assembly 223 is installed in the second mounting groove 2222. The carrier seat 222 is provided with a second mounting hole 2223 in the vertical direction, and the transmission assembly 224 can be installed in the second mounting hole 2223 in a manner of being lifted and lowered in the vertical direction.

[0049] The length direction of the carrier seat 222 is parallel to the recessed direction of the first mounting groove 211, and the first mounting hole 2221, the second mounting groove 2222 and the second mounting hole 2223 are arranged side by side along the length direction of the carrier seat 222, and the first mounting hole 2221 is close to the slot opening of the first mounting groove 211, the second mounting hole 2223 is close to the bottom of the first mounting groove 211, and the second mounting groove 2222 is located between the first mounting hole 2221 and the second mounting hole 2223.

[0050] The cover plate assembly 223 includes a cover plate 2231 and a connecting column 2232. The two ends of the connecting column 2232 are fixed to the two opposite inner walls of the second mounting groove 2222. The cover plate 2231 is sleeved outside the connecting column 2232 and can slide along the connecting column 2232. In this embodiment, the axial direction of the connecting column 2232 is parallel to the width direction of the carrier seat 222. The cover plate 2231 is received in the second mounting groove 2222 and sleeved outside the connecting column 2232. The cover plate 2231 partially extends out of the second mounting groove 2222 to form a cover portion, which covers the top of the socket 221. The cover portion is suitable for sliding along the axial direction of the connecting column 2232 to cover or open the receiving groove 2211.

[0051] Preferably, there are two cover plates 2231, which are arranged side by side along the width direction of the carrier seat 222. The two cover plates 2231 are adapted to move toward each other under the drive of the transmission assembly 224 to cover the receiving slot 2211, or move away from each other to open the receiving slot 2211. By adopting the above structure, the moving path of a single cover plate 2231 can be reduced, and the opening and closing efficiency can be improved.

[0052] The transmission assembly 224 includes a transmission plate 2241, a second follower 2242 and a third reset member 2243. The transmission plate 2241 can be received in the second mounting hole 2223 in a vertically movable manner. The transmission plate 2241 is provided with guide holes 2244 along the length direction of the carrier seat 222. There are two guide holes 2244, which correspond to the cover plate 2231 one by one. The guide holes 2244 are bar-shaped holes. The two guide holes 2244 are arranged in an eight-shaped shape. The distance between the upper ends of the two guide holes 2244 is smaller than the distance between the lower ends. A notch 2224 is provided between the second mounting groove 2222 and the second mounting hole 2223. The second follower 2242 is fixed to the cover plate 2231 and is at least partially embedded in the guide hole 2244 through the notch 2224. The second follower 2242 corresponds to the cover plate 2231 and / or the guide hole 2244 one by one. The transmission plate 2241 has a convex portion 2245 opposite to the bottom of the carrier seat 222. The third reset member 2243 is specifically a spring, and its expansion and contraction direction is parallel to the vertical direction. The third reset member 2243 is held between the bottom of the carrier seat 222 and the convex portion 2245. The third reset member 2243 is suitable for providing a force to drive the transmission plate 2241 to move downward, and to make the second follower 2242 abut against the upper end of the guide hole 2244. The switching mechanism 230 is suitable for lifting the transmission plate 2241, and the guide hole 2244 is suitable for rising to drive the two cover plates 2231 to move back to the open state, and when the switching mechanism 230 is lowered, the guide hole 2244 is suitable for descending under the rebound action of the third reset member 2243 to drive the cover plates 2231 to move toward each other to the closed state.

The number of electrical testing devices 300 is specifically N, and the number of carrier mechanisms 220 is specifically 2N. The product is a photosensitive chip, and the electrical testing device 300 needs to irradiate light on the photosensitive area of ​​the product to perform a photosensitivity test.

The connecting rod mechanism 340 is suitable for driving the electric measuring mechanism 320 and the light source mechanism 330 to move toward or away from each other in the vertical direction under the drive of the connecting rod driving member 350. The connecting rod mechanism 340 includes a rotating shaft 341, a lever 342, a short connecting rod 343 and a long connecting rod 344.

[0058] Furthermore, the first turntable 110 is suitable for driving the nozzle mechanism 120 to sequentially move to the loading station, the transfer station, the appearance inspection station and the unloading station.

The appearance inspection device 500 is arranged at the appearance inspection station and is used to inspect the appearance of the product. The unloading device 600 is arranged at the unloading station and is suitable for unloading the product. After the product on the sub-tower device 200 is subjected to electrical testing, the main tower device 100 is suitable for taking the product off the sub-tower device 200 at the transfer station and transferring it to the appearance test station and the unloading station in sequence.

[0059] The feeding device 400 is a vibrating plate feeding structure, and the appearance inspection device 500 uses a camera to shoot the outer surface of the product to obtain its appearance information, which will not be described in detail in the present invention. The unloading device 600 includes a sorting mechanism 610, a braiding mechanism 620 and a first waste discharge mechanism 630. The sorting mechanism 610 is used to receive qualified products and store them by category, the braiding mechanism 620 is used to receive qualified products and braid them, and the first waste discharge mechanism 630 is used to receive unqualified products.

[0060] The sorting mechanism 610 includes a second mounting frame 611, a hopper 612, a first material pipe 613, a sorting drive 614 and a first material box 615. The hopper 612 is arranged on the second mounting frame 611 to receive the product dropped by the suction nozzle mechanism 120. The first material pipe 613 is rotatably connected to the second mounting frame 611, one end of which is located directly below the hopper 612 to be connected to the bottom of the hopper 612, and the other end extends downwardly at an angle. The first material box 615 is located below the first material pipe 613, and there are multiple first material boxes 615 with open tops. The first material pipe 613 responds to the rotation operation so that its lower end corresponds to the top of different first material boxes 615, and multiple first material boxes 615 are suitable for accommodating different categories of products. The sorting drive 614 is a rotating motor, which is transmission-connected to the first material pipe 613 through a belt structure 616 to drive it to rotate.

[0061] Furthermore, the tape-taping mechanism 620 is an existing chip tape-taping machine, which will not be described in detail in the present invention. The first waste discharge mechanism 630 includes a material box frame 631 and a second material box 632. The side of the material box frame 631 is an open side for taking and placing the second material box 632. The top of the material box frame 631 is provided with a second material pipe 633. The second material pipe 633 extends into the material box frame 631 to correspond to the top open side of the second material box 632. The nozzle mechanism 120 is suitable for putting unqualified products into the top of the second material pipe 633, and the products can fall into the second material box 632 under the guidance of the second material pipe 633.

[0062] Since the feeding device 400 is a vibrating plate feeding structure, it is difficult to position the product, resulting in poor positioning accuracy of the product after the suction nozzle mechanism 120 absorbs the product. As a preferred embodiment, an adjustment station is provided between the feeding station and the transfer station, and the fully automatic electrical testing system includes an adjustment device 700 provided at the adjustment station, and the adjustment device 700 includes a direction determination mechanism 710, a rotation adjustment mechanism 720, and a second waste discharge mechanism 730. The direction determination mechanism 710 is suitable for photographing the product on the suction nozzle mechanism 120, the rotation adjustment mechanism 720 is suitable for receiving the product on the suction nozzle mechanism 120, and adjusting the position of the product according to the photographing result of the direction determination mechanism 710, and the second waste discharge mechanism 730 is suitable for receiving unqualified products. After the suction nozzle mechanism 120 absorbs the product on the feeding device 400, the first turntable 110 is suitable for driving the suction nozzle mechanism 120 to flow through the direction determination mechanism 710, the rotation adjustment mechanism 720, and the second waste discharge mechanism 730 in sequence. The direction determination mechanism 710 is a visual structure, which is located below the suction nozzle mechanism 120 to obtain the position image of the product. At the same time, the direction determination mechanism 710 can also perform a rough inspection of the appearance of the product to eliminate obviously unqualified products. The rotation adjustment mechanism 720 is a rotating adsorption table, which is suitable for receiving products and rotating around an axis parallel to the vertical direction to adjust the angle of the product. The suction nozzle mechanism 120 can remove the product after the position is adjusted. The structure of the second waste discharge mechanism 730 is the same as that of the first waste discharge mechanism 630. Qualified products with adjusted angles can be transferred from the suction nozzle mechanism 120 to the carrier mechanism 220, and unqualified products can be put into the second waste discharge mechanism 730.

[0063] The working process of the fully automatic electrical testing system of the present invention is as follows: the suction nozzle mechanism 120 is driven by the first turntable 110 to move to the loading device 400 to absorb the product to be tested; then the suction nozzle mechanism 120 is sequentially transferred to the direction determination mechanism 710, the rotation adjustment mechanism 720 and the second waste discharge mechanism 730. At the direction determination mechanism 710, the direction determination mechanism 710 can take a picture of the product to obtain the position of the product. The rotation adjustment mechanism 720 can receive the product on the suction nozzle mechanism 120 to rotate and position the product. If the product is unqualified, the suction nozzle mechanism 120 does not need to place the product on the rotation adjustment mechanism 720, and it can directly put the product into the second waste discharge mechanism 730; then the suction nozzle mechanism 120 takes out the positioned product and transfers it to the transfer station to place the product on the carrier mechanism 220. The above-mentioned actions are repeated until the N carrier mechanisms 220 are all loaded with products. At this time, the N carrier mechanisms 220 loaded with products correspond one-to-one to the electrical measuring devices 300. With the rotation of the second turntable 210, multiple electrical measuring devices 300 can simultaneously perform electrical tests on the products. The carrier mechanism 220 carrying the tested products is transferred back to the transfer station, and the nozzle mechanism 120 takes the products off the carrier mechanism 220 and transfers them to the appearance inspection device 500, the sorting mechanism 610, the taping mechanism 620 and the first waste discharge mechanism 630 in sequence. The appearance inspection device 500 can perform appearance inspection on the products after the electrical test. Qualified products can be selectively flowed into the sorting mechanism 610 or the taping mechanism 620 according to actual needs to achieve sorting or taping, and unqualified products can directly flow into the first waste discharge mechanism 630.
